Ultra high definition video image processing and transmitting system and method thereof

Abstract

The invention discloses an ultra high definition video image processing and transmitting system which comprises an input module, a video processing unit and a display unit, wherein the input module receives ultra high definition digital video images, an output end of the input module is connected with an input end of the video processing unit, and an output end of the video processing unit is connected with an input end of the display unit; a controller and a time sequence control module which are connected to each other are arranged in the display unit. According to the ultra high definition video image processing and transmitting system, segmentation and compressing processes are carried out on image frames of the ultra high definition video images after decoding, merge application is carried out on the image frames in the display unit through asynchronous transmission, then the image frames are further amplified to be restored to original signals, and transmission and playing displaying for the ultra high definition signals are achieved. According to the processing method, the transmission data bandwidth can be compressed, the transmission bandwidth is further reduced, 4K2K ultra high definition video image transmission is achieved due to the fact that data are transmitted through an FHD interface, and the effect of transmission of a large number of ultra high definition video image data is achieved.

Description

technical field [0001] The invention relates to the field of video image processing and transmission, in particular to a system and method for ultra-high definition video image processing and transmission. Background technique [0002] At present, TVs and monitors are developing in two directions of large size and high image quality, and large size and high image quality must require higher resolution display, which brings the development of high resolution technology. However, a higher resolution display requires higher resolution video images, and these images need to be transmitted to the LCD screen for display, requiring greater bandwidth and other resource support. [0003] Traditional LVDS signals need two groups to support FHD60Hz output, and four groups support FHD 120Hz output. If you want to support 4K2K (3840×2160 physical resolution) LVDS signal output, you need to provide 4 times the bandwidth; if you want to support 4K2K ( 3840×2160 physical resolution) 60Hz L...

Problems solved by technology

In this way, FHD 60Hz needs 2 sets of LVDS signals, 6 pairs of data lines, a total of 12 wires for transmission; FHD 120Hz requires 4 sets of LVDS signals, 24 pairs of data lines, a total of 48 wires for transmission. Under this condition, 4K2K 30Hz signals can be transmitted at the same time; if To transmit 4K2K 60Hz signals, you need 8 sets of LVDS signals, 48 ​​pairs of data lines, a total of 96 wires for transmission, to support such a large data bandwidth, and so many data lines connected by wires will bring cost and difficulty in operation increase, but to transmit images of higher resolution levels, this transmission method cannot meet the transmission requirements

[0005] In addition, due to processing capacity limitations and resource requirements, many chips are still unable to directly support the decoding, playback and transmission of 4K2K ultra-high-definition native images.

At the same time, many interfaces currently only support FHD transmission interfaces, but cannot directly support high-resolution signals such as 4K2K.
